ide: Fix file references in drivers/ide/

2011-10-13T06:25:11Z

Fix file references in drivers/ide/ There are a lot of file references to now moved or deleted files in the whole tree, especially in documentation and Kconfig files. This patch fixes the references in drivers/ide/. Signed-off-by: Johann Felix Soden Signed-off-by: Randy Dunlap Acked-by: David S. Miller Signed-off-by: Linus Torvalds

ide-disk: Fix request requeuing

2011-10-03T18:28:18Z

Simon Kirby reported that on his RAID setup with idedisk underneath the box OOMs after a couple of days of runtime. Running with CONFIG_DEBUG_KMEMLEAK pointed to idedisk_prep_fn() which unconditionally allocates an ide_cmd struct. However, ide_requeue_and_plug() can be called more than once per request, either from the request issue or the IRQ handler path and do blk_peek_request() ends up in idedisk_prep_fn() repeatedly, allocating a struct ide_cmd everytime and "forgetting" the previous pointer. Make sure the code reuses the old allocated chunk.

drivers/ide/cy82c693.c: Add missing pci_dev_put

2011-08-04T08:30:34Z

Pci_get_slot calls pci_dev_get, so pci_dev_put is needed before leaving the function in the case where pci_get_slot is locally used. The semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // @@ local idexpression x; expression e; @@ *x = pci_get_slot(...) ... when != true x == NULL when != pci_dev_put(x) when != e = x when != if (x != NULL) {<+... pci_dev_put(x); ...+>} *return ...; // Signed-off-by: Julia Lawall Signed-off-by: David S.

ide: Fix irq flags madness

2011-08-04T08:29:51Z

commit ec1a123 (IDE: pass IRQ flags to the IDE core) introduced the bogosity of passing unfiltered resource->flags to the irq_flags which are used for request_irq. It results in random bits set (especially IORESOURCE_IRQ which maps to IRQF_PER_CPU). Filter the bits proper. Signed-off-by: Thomas Gleixner Signed-off-by: David S. Miller

Merge branch 'master' into for-next

Sync with Linus' tree to be able to apply pending patches that are based on newer code already present upstream.

ide-cd: signedness warning fix again

2011-06-11T22:06:48Z

One of the legit warnings 'make W=3 drivers/ide/ide-cd.c' generates is: drivers/ide/ide-cd.c: In function ide_cd_do_request drivers/ide/ide-cd.c:828:2: warning: conversion to int from \ unsigned int may change the sign of the result drivers/ide/ide-cd.c:833:2: warning: conversion to int from \ unsigned int may change the sign of the result nsectors is declared int, should be unsigned int. blk_rq_sectors() returns unsigned int, and ide_complete_rq expects unsigned int as well. Fixes both warnings. Signed-off-by: Connor Hansen Signed-off-by: David S. Miller

treewide: Convert uses of struct resource to resource_size(ptr)

2011-06-10T12:55:36Z

Several fixes as well where the +1 was missing. Done via coccinelle scripts like: @@ struct resource *ptr; @@ - ptr->end - ptr->start + 1 + resource_size(ptr) and some grep and typing. Mostly uncompiled, no cross-compilers. Signed-off-by: Joe Perches Signed-off-by: Jiri Kosina

block: fix mismerge of the DISK_EVENT_MEDIA_CHANGE removal

2011-06-01T20:29:19Z

Jens' back-merge commit 698567f3fa79 ("Merge commit 'v2.6.39' into for-2.6.40/core") was incorrectly done, and re-introduced the DISK_EVENT_MEDIA_CHANGE lines that had been removed earlier in commits - 9fd097b14918 ("block: unexport DISK_EVENT_MEDIA_CHANGE for legacy/fringe drivers") - 7eec77a1816a ("ide: unexport DISK_EVENT_MEDIA_CHANGE for ide-gd and ide-cd") because of conflicts with the "g->flags" updates near-by by commit d4dc210f69bc ("block: don't block events on excl write for non-optical devices") As a result, we re-introduced the hanging behavior due to infinite disk media change reports. Tssk, tssk, people! Don't do back-merges at all, and *definitely* don't do them to hide merge conflicts from me - especially as I'm likely better at merging them than you are, since I do so many merges.
